To rtZZ whom/flit wea concern:

Beit known that I, EDWIN J. SnL'LEY, of

the city, county, andv State of New York,

have inventeda new and Improved Stove or full, clear, and exact description.

\ My invention relatesito improvements in stoves or furnaces which burn coal; and the object of my invention is to produce a structure of simple desi n which is very much more efficient than t e ordinary coal-burning stove or furnace, for the reason that ithas an independent burner or mixing-chamber for gas thrown, off by the coal and for the'coal itself,'or rather for the carbon.

My invention is further intendedv to produce a structure which is comparatively in eXpensive,.which will produce a great deal of heat from a given quantity of fuel, and

which can be advantageously used to generate steam or heat water, particularly so the water-heating meansserves the further purpose a of supporting the fuel-body. In

this way I economize space and material as well as fuel and am able to make my heating coil do double work, as will hereafter appear.

A further object of my invention is to arrange the draft of the gas-burning part of the 1 device so that it can be mad'e'practically a forced draft, if desired, and so. that the right admixture of air with the gas can easily be .made.

To these ends myinvention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed. n. Reference is to be hadto the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views;

Figurel is a vertical section of a stove' or heater embodying my invention. 2 is 'a cross-section on the hue 2 2 of Flg. 1.. Flg. 3 18 a, similar section, but showing only a portion of rods forming the heater orstove sides- .and illustrating a shutter-like means for mclosing the sides. Fig; 4 is a cross-section on the hue 4 4 of Fig. 1. Fig. 5 1s a cross-section on the line 5 5 of Fig. 1. 'Fig. 6 is a detail of a modified means A for regulating the air-intake. Fig. 7 is a cross-section on the line 7 7 of Fig. 1. .Fig. 8 is a cross-section on the line 8 8 of Fig. 1.

The heating device, which, as stated, can be either a stove or furnace, has a fire-box spaced and strengthened by the rings 11,

ducing a slat-like or cagelike'structure, and

a base-ring 12, which can be mounted on legs 13 or can be v supported n any convenient at the top the "fire-box has a suitable cash ing 14 in the formof a ring, into. and through pyhich'the coal can be shoveled to the fire- The coal body is supported on a coil of pipe I 15, which can have any usual water connections for circulation purposes, and as the members of the coil are spaced apart slightly the coil serves the purpose of a grate in supporting the fuel, and as it is in actual contact with a body of'live coals it will be quickly and efliciently heated. This is especially located just below the pi.pe-'coil, and the finer particles will settle through the coil upon the grate 16, so that the coil will be actually em bedded in coals to a certain extent.

The grate 16 can be of'any approved construction, and it has a handle 17 extending it can be conveniently shaken. r

In Fig. 3 I have'shown a means for inclosing the firebox; but in this structure I have shown only a portion of the rods 1.0 and a corresponding number of narrow shutters 19, which are pivoted on the outer sides of the fire-box, and these can be closed, as at the top in Fig, 3, partly open, as at the right-handof the same figure, or open Wide, as shown in the bottom of the same figure. can admit more or less air, as required, to,thesides of the fire box, and so regulate the draft and the amount of heat radiated.

the stac 20, which extends vertically through the fire-box and. wellibelow it to insure a powerful draft, and has means for admitting air at the bottom and has also numerous perforations 2O opposite the fuel-bed as Wlll be burning in the stack while the carbest results, means must be employed for reg ulating the admission of air to-the stack, and I have found that by reducing the stack at a point below the heater-bod y, as shown at 20,

thus producing a-double-funnel effect or the effect of opposed frustums of cones with then formed of the vertical rodsv 10,: which are at the bottom the fire-box is supportedon way which will permit the ingress of air, and

In this way I An important feature of the inventionis (T hon is burning in the coal mass. To get the through which the rods extend, thus protrue because ofthe lower grate 16, which is through an opening 18 in. the ring 12, so that a through which the gas can pass, and so the ITO shown comprises in part a s I smaller ends together, the air-draft is greatly increased, and in fact can be made very strong. A similar effect can be had by leaving the stack 20 full size and putting reducingplates 21 within it, as shown in Fig. 6. The

articular structure set forth is all right; but it will work as Well even if the smaller ends of the funnel portions of the stack are removed sli htly from each other.

0 still further regulate the air intake,

, which opening can be regulated by a needlevalve 24, which extends into it. The needlevalve 24 has its stem 24 connected to a handle 25, which is mounted in a sleeve-nut 26,.

which fits in the thread of the shell 22 and which has numerous air-openings 27. (See Figs. 1 and 8.)

tube or stack 20 can be nicely controlled, and the construction of the stack or tube above the valve causes the air to be sucked in very fast, after which it mixes with the gas passing through the openings 20 and is burned in the upper part ofthe stack or tube 20, which serves as a-mixing-chamber.

From the foregoing description it will be readily seen that the design which Ihave shown is not very material, that the essential thing is to have a cage-like fire-box with what is practically a Bunsen tube extending v vertically through it and with means for regulating the air intake and alsofor using the fuel-support as a water-heater. It will be of course clearly understood that thestove .or

furnace or heater which I have shown and described can-be, adapted for many purposes, either as a heater of some'specific thing or as a heat-radiator.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A stove or furnace comprising a fire-box having a Bunsen tube or stack extending vertically through it, said stack having I means for admitting gas from the fire-box and being reduced in diameter below thev Thus b I regulating the needle-val've the amount 0 a r admitted to the 2.
